Difference between map and maf sensors

WebMAF and MAP Sensors The ECM and the TCM monitor engine load through the MAP and MAF sensors. The (MAP) manifold absolute pressure sensor senses engine load through pressure in the intake manifold. A … WebMay 9, 2007 · The front O2 sensor is ONLY used during closed loop fueling (idle & cruising), when in the boost (Open Loop) the MAF is used. Typically as boost increases, MAF flow increases, the ECU adds fuel as MAF flow increases. Boost pressure is irrelevant as far as fueling is concerned. Flow is what determines how much fuel you need. 1988 …
